Barrett esophagus (BE) is the precursor lesion to adenocarcinoma of the esophagus. The current surveillance strategy of 4-quadrant Seattle protocol biopsies has been associated with sampling error and missing higher-risk lesions, and there is often less adherence to endoscopic surveillance with long segments. Advancements in endoscopic imaging and sampling techniques allow for better surveillance of BE, particularly when assessing for dysplasia. This article highlights the key endoscopic imaging and sampling advancements in the evaluation of dysplasia in BE.
